To all whom, 'it may amm: I Be it known that I, JoHN W. JONES, cit-izen of the United States, residing at Rooseplenum principle and are designed to prevent the air in the various rooms or parts of a buildin from becoming vitiated, by continually orcing a fresh sup ly of air therein, without causing any dra s in the rooms, as would be dangerous or annoy the occupants thereof, and the object of the invention is 'an improved a paratus of this character which is most e cient in operation and which is simple and durable in construction and may be conveniently installed at a minimum cost. Y

With this and other objects in view that will more fully 4appear as the description proceeds, the invention consists in certain constructions and arrangements of the parts -that I-shall hereinafterfully describe and then point out the novel features thereof in the appended claim,`

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying-drawing, in which;

Figure l is a cross sectional view of a building equipped with my improved ventiu latin system; and, Fig. 2 is a detail View of the an,.showing Jche form Vof screened in- 'take employed when the fan is located on i the. exterior of the building. l

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.,

In carrying out my invention, I'provide a blast fan l which may be of any desired or approved construction or design and which may be turned by ahy suitablae motor (not shown), the fan being placed without the building, or being located in an osition found most convenient or desirab e 1n practice, although tpreferably upon4 theroof, as.

shown. This an 1 is provided with al supply of fresh air by means of an intake 2 which establishes communication between the exterior of the building and the interior of the fan, and which is preferably screened, as indicated at 3, for a purpose to' be hereinafter disclosed. F rom the fan l, fresh air is forced through a main supply pipe or air duct 4 which extends into the varionsrooms or parts of the building to be ventilated, one or more distributing pipes 5 Vleading from the main su ply pipe 4 in each room of the building, an being preferably perforated, as indicated at 6, so as to provide means of escape for the fresh air. In practice, ithas been found desirableto locate the rooms.

Attention is particularly directed to the v fact that the perforations-or outlets are arranged in two longitudinal series, the said series being positioned diametrically oppositely to each other and being disposed ina vertical plane. The distributing pipes are otherwise imperforate. By virtue of such a construction fresh air escaping through the perforations of the lower series' is directed vertically downwardly into the room, while the air passing through the upper perforations is directed against the ceiling and is deliected laterally thereby, so. as to be distributed efectnally to all parts of the room.

From the foregoing description, in con-Y nectiouwith the accompanying drawing, it

these distributingl pipes near the ceilings of will be apparent that I have provided an improved Ventilating system by means of which. fresh air may be supplied to the various rooms of a building, near the ceilings of the same, so as to forcibly eject or exhaust any foul -air collected in the rooms and maintain proper sanitary conditions in thesame, said Ventilating apparatus being simple and durable in its construction, and consisting of comparatively few parts that may be easily and cheaply manufactured i and readily installed in a building.' Inasmuch as the intake is screened, as indicated at 8, the admission of any foreign substances, such as dust or bugs or the like to the interior' of the blast fan, is e'ectually precluded, and'this manifestly prevents the possibility of the fan becoming clogged with such particles, or the liability of the latter Ybeing forced through the air ducts and discharged into vthe various rooms ,of the building.

Having thus described the invention, what I claim is:

The combination with a buildingof e Ventilating system of the' character de scribed comprising a fan mounted on the rooi:l of the building and provided with a screened intake to exclude foreign particles, a fresh-air supply pipe havingvconnection with the fan and extending downwardly through the floors of the building, and distributing pipes connected to the supply pipe and leading therefrom into the respective rooms on each floor7 the distributingr pipes bein arranged in proximity to the ceilings of t e rooms and being imperforete with the exception of upper and lower longitueeeeee dimi series of outlets extending therethrough et diametrically opposite points, the series of outlets of euch distributing pipe being disposed in a vertical plane, the lower outlets directing 'the fresh eil" vertically downwardly into 'the room and the upper outlets directing the fresh air e. einst the ceiling of the room.:v whereby the airjs deflected laterally by the ceiling to insure of the thorough distribution thereof'.

in testimony whereof l aiiix my signature in presence of two Witnesses.
